电力机车司机室空调系统降温速率分析

Study on Rate of Temperature Drop of Air Conditioning System in Electric Locomotive Cab

介绍了电力机车司机室空调系统降温试验 ,在整理大量数据的基础上 ,提出了机车空调系统降温曲线的数学表达式 ,进而推导出空调系统的降温速率表达式 ,引出一个评价空调系统的降温特性的参数———降温系数λ。从定性和定量两方面分析了降温系数 ,并给出了其物理意义。

This paper introduces the test of temperature drop in electric locomotive cab. On the basis of many test data, it puts forward the mathematical correlation of the temperature drop curve, and leads to a parameter-coefficient of temperature drop(λ) to evaluate the property of temperature drop of air conditioning system. This paper analyzes the coefficient of temperature drop by quantitative analysis and qualitative analysis, and shows its physical essence. Such work is helpful to the intensive research of property of temperature drop of air conditioning system.
